12dpo and cramping

Heather
I'm 12dpo and cramping really bad on the lower left side of my stomach. Is this a bad sign? This is my first month after clomid. We've been ttc for 16 months. I think I may have gotten a vvvf positive 2 days ago... I'm waiting a Few days to test again but I need help! Would it be dumb of me to ask for a blood test?
